Posted this question on the general zones group at got a deafening silence in 
response - anyone here have any possible answers?

It is possible that prstat and rcapd are counting shared memory multiple times,
so that it seems like you are using more memory within the zone.  This is
a known bug:

4754856 *prstat* prstat -atJTZ should count shared segments only once

We are working on an enhancement to zones and resource management which
will improve a bunch of things in this area, including the way rcapd
accounts for shared memory.  It will also allow you to solve your underlying
problem by running a single rcapd in the global zone which will cap each
zones memory consumption.  This is described in this thread:

Let us know if you have any questions about this project.
